| 摘 要： | 合成了金属元素Mg、Al取代的缺位型Dawson结构磷钼钨杂多化合物MP2W15Mo2(M=Mg,Al等),并以其为催化剂,用30%的过氧化氢为氧化剂,在水-苯甲醇的两相体系中进行了苯甲醇的催化氧化反应.通过正交实验对苯甲醇催化氧化条件进行了考察,结果表明,催化剂MgP2W15Mo2的催化效果最好,其最优反应条件为:温度100℃,催化剂用量为2.5μmol,反应时间10 h,30%双氧水用量1 mL(9.79 mmol). |

| Abstract: | A series of metal-substituted lacunary Dawson-type molybdotungstophosphoric compounds MP2W15Mo2(M=Co,Ni,Cu,Zn,Fe,Mn,Mg,Al)were synthesized.The catalyzed oxidation of benzylalcohol to benzaldehyde in water-benzylalcohol biphasic system,using hydrogen peroxide aqueous solution as oxidant,has been investigated in detail.The orthogonal test of catalytic oxidation of benzylalcohol has proved that MgP2W15Mo2 was the best catalyst and the optimum reaction condition was also confirmed. |
| Keywords: | Heteropoly compound Catalysis Oxidation Benzyl alcohol Benzaldehyde |
